Mossberg 500 small parts

[JBob77]

I am looking for a Mossberg 500 ejector screw and trigger housing pin. My shotgun had a Weaver mount on the side, requiring both to be longer than factory. I am looking to remove the lower half of it, but need the correct parts, so they don't protrude from the receiver. I also have the mount if anyone is interested in it. I am surely not.
